The bdevio test app has some test cases verifying
that write zeroes commands are handled correctly,
but using knowledge of the ZERO_BUFFER_SIZE that
the bdev library uses for splitting larger write
zeroes commands. Instead of hardcoding that 1MB
value in bdevio.c, have bdevio.c use ZERO_BUFFER_SIZE
directly instead. But this requires moving
ZERO_BUFFER_SIZE into bdev_internal.h and having
bdevio.c include that file.
We do this instead of putting ZERO_BUFFER_SIZE in
the public API because we don't want users to
make any kind of dependencies on this value.
While here, also rename the tests that are using this
value, so that the test names don't include any reference
to the specific size of this bdev-internal zero buffer
size.

This patch adds process_virtio_blk_request() that will be called
by virtio_blk transports to process incoming requests.
Meanwhile vhost_user_blk_request_finish() will be replaced with
a callback to the virtio_blk transport to notify of the result.
blk_request_finish() should only be called as direct result of
process_virtio_blk_request(), usually from it.
Some error paths now call vhost_user_blk_request_finish() directly,
if vhost_user_process_blk_request() was not called yet.

As per the NVMe specification, a host can identify two areas of guest
memory: one of which is used for the host-written doorbells, and one of
which contains event indexes. The host writes to the shadow doorbell
area, but also writes to the controller's BAR0 doorbell area if the
corresponding event index is crossed by the update. This avoids many
mmio exits in interrupt mode, where BAR0 doorbells are not directly
mapped into the guest VM, with greatly improved performance.
This isn't a useful feature in BAR0 doorbells are mapped into the VM, so
we explicitly disable support in that case.
NB: the Windows NVMe driver doesn't yet support this feature.
Although the specification says that the admin queues should also engage
in this behaviour, in practice, no VM does, so have to include some
hacks to account for this.

We may fail creating qpair when adding io_path while creating a bdev_channel
if connection is down. But if we enable I/O error recovery, we can retry
creating qpair later.
So let nvme_qpair_create() succeed if the ctrlr is being reset or
I/O error recovery is enabled even if creating qpair failed.

Previously, only if admin qpair gets error, bdev_nvme_failover() was
called.
However, I/O qpair may get error earlier than admin qpair. In this case,
bdev_nvme_failover() was called but reset was already in progress. So
bdev_nvme_failover() returned without doing anything.
bdev_nvme_reset_complete() executes bdev_nvme_failover() if reset
failed. However the test time of test/nvmf/host/failover.sh was very
short. Timeout came before trying bdev_nvme_failover().
We can replace other bdev_nvme_reset() calls by bdev_nvme_failover()
but this patch focuses on the critical case.
Fixes issue #2128.

When a qpair is disconnected, any outstanding zero-copy requests are
freed to release their buffers before the qpair gets destroyed.
However, if there is a PDU being sent to the host as part of this
request (e.g. C2HData/R2T), we need to wait until that write is done
before freeing the request to avoid freeing it twice.
